This wasn't the first time Josiane has sung the national anthem before one of her big brother's games.
"We started that [singing the anthem] when I was in junior and she was probably 14 at that time, even younger, actually," Huberdeau said about his sister. "Just in Florida she sang a lot against Montreal. A lot of family was at the game, so we just thought it was cool. Now she's been asking me every year, so then when I got traded here, she's like 'ah, you can ask if I can sing.' That's a good idea, and the first game she is here so I might as well ask and the Flames have been great and they said yes."
Unlike his sister, Huberdeau gets a little stage fright when it comes to his own musical skills.
"I love to sing," Huberdeau said. "But just in the shower."
